Description
Technical field
The invention belongs to technical field of auxiliary equipment during electrician's erecting power lines, particularly the fast take-up and pay-off device of the adjustable applicable different model cable hank of a kind of length and width and using method.
Background technology
Power line product is electric power drum power line is wrapped on reel, and with a large amount of power lines during erection high-altitude power line, power line disk body is long-pending comparatively large, and weight is also comparatively large, and during unwrapping wire, reel must rotate.In order to realize, with power line dish unwrapping wire, electric power drum will being put on power line pay off rack during unwrapping wire.Power line pay off rack is mainly used in supporting electric power drum and is beneficial to unwrapping wire.
In transformer station secondary system construction, the workload of cable laying occupies the main engineering time.Current cable unreeling rack is all adopt column support type pay off rack, include base, two column and roller bearing, two column symmetry installs the both sides being placed on base, roller bearing is connected to the intermediate shaft hole of two column, and when changing cable hank, base needs lifting to support cable hank, then roller bearing is pulled down, put down base, utilize hoisting equipment or manpower to unload cable hank, and load onto new cable hank; After new cable dish is loaded onto base, base needs to promote new cable dish, until the axis hole of cable hank is corresponding with two column axis hole, finally loads onto roller bearing, completes the replacing of cable hank.Need the diameter adjustment level height according to cable hank in addition, topple over to prevent cable hank, these wire-unfolding rack complex structures, mobile inconvenience, in use need loop wheel machine to be lifted on support by cable hank, and working costs is taken a lot of work and needed to want many people carry out compounding practice.
Due in cable laying work progress, after ensureing cable laying, ditch inner cable is attractive in appearance, need the cable hank changing different size frequently, use existing pay off rack, due to complex procedures, device structure is loaded down with trivial details, even need auxiliary equipment, therefore exist and change dish speed slowly, take a large amount of engineering times; In addition, change dish at every turn and nearly all will regulate its level height, therefore those skilled in the art also adopt how secondary pay off rack to configure the cable hank of different-diameter, but so, how secondary pay off rack can take construction passage, cause construction inconvenient.
CN201110355299.9 discloses a kind of wire payoff rack for transmission line, it comprises wire wheel disc, roller, support, base and brake gear, wire wheel disc is bearing on the roller set by four supports difference, and every two supports are placed on two row's bases respectively, is provided with brake gear below wire wheel disc across asking in two row's bases.Brake gear is lever-type structure, comprises brake block and depression bar support bar set by depression bar, depression bar the inner, totally two covers, and integral seat falls within asking of two pack supports, is loaded on respectively on two bases.Its weak point is: in use need loop wheel machine to be lifted on support by cable hank, and working costs is taken a lot of work and needed to want many people to carry out compounding practice.
And for example rolling type cable unreeling rack disclosed in CN201120456112.X, it is characterized in that, include with base, two roller and brake device of rolling wheels, one side of base is a kind of slope, slope extends earthward, two roller is arranged on the platform of base, and the distribute spacing of two roller is greater than 40% of cable hank diameter, and brake device of rolling wheels is arranged on one of them roller in two roller.Its weak point is: in use need to shift onto between platform roller by cable hank frequently, need staff existing platform is fixed on the ground and ensure two bases platform parallel and between the roller that neatly cable hank just can be made to push smoothly on platform, change the cable hank of different size frequently, just need to adjust the spacing between platform frequently and dismounting and fixed platform, use extremely time-consuming taking a lot of work; Injure other people by a crashing object because cable hank heavily needs multiple personnel to carry out promoting easily to cause cable hank to rout up in pushing course simultaneously, at least need 5 staff under normal circumstances, promotion is wasted time and energy, cable hank difference is pulled down, the cable hank of another different model that changes the outfit uses said apparatus to need at least 3 hours, operating efficiency is low, and pulls wire rotation to waste time and energy.
Summary of the invention
